Disambiguation of false touch inputs at an information handling system projected user interface

摘要: Inputs to a projected or other type of displayed user interface are verified with verification device that enhances input detection accuracy. For example, inputs at keyboard detected by an infrared curtain over the and breached end finger as it strikes key. The capacitive sensor disposed below confirms touch. Alternatively, proximity sensing measures distance velocity associated verify breaching intended inputs. Other devices may include accelerometer detects accelerations three dimensional cameras capture positions. Verification be selectively enabled based upon power accuracy constraints.
